Slow it down! Get the RPM down to around 175-225 and you need some kind of cutting fluid to help. If that is a piece of 41xx and heat treated, you need to cut the RPM's in half, just my rule of thumb I use.
Thanks Ken. I'll give the slower speed a shot on the next attempt plus I'll brush on some of the Rapid Tap fluid until I can get some proper cutting oil.
Pretty sure it's not heat treated steel. Not positive though. I can easily file this, even after milling it.
